LLMLingua: budgeted coarse-to-fine prompt compression

Combined a prompt-component budget controller, iterative token compression and small-model distribution alignment to compress inputs for an otherwise black-box language model.

What is recorded here?

Combined a prompt-component budget controller, iterative token compression and small-model distribution alignment to compress inputs for an otherwise black-box language model.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

Inherits selective-context/self-information compression. Removing low-perplexity tokens does not guarantee preserved meaning or answers on arbitrary inputs. Compression-model tuning/compute costs remain and historical API price savings are not current prices.

Read the original work

This English explanation is an editorial reading view. It does not replace the complete original work or certify its science.
